This tutorial will demonstrate how to connect the B-Alert X24 EEG headset to your computer and PhysioLab\ :sup:`XR`.
The `B-Alert Mobile <https://www.advancedbrainmonitoring.com/products/b-alert-mobile>`_ by `Advanced Brain Monitoring <https://www.advancedbrainmonitoring.com/>`_ is a wireless, research-grade EEG system with real-time impedance checks and SDK integration. Common configurations provide 20 EEG channels, and samples at 256 Hz.
This tutorial will be primarily focused on the Windows platform.

1. Turn on the BAlert.
2. Launch PhysioLab\ :sup:`XR`.

Color legend
• Green (< 40 kΩ): Good
• Yellow (≥ 40 kΩ and < 80 kΩ): Moderate — improve contact / add gel
• Red (≥ 80 kΩ): Bad — fix contact
• Gray (NA): Out of range / no contact

.. note:: Proceed only when all EEG channels are green.
